Product description

The Heidenhain 557 679-10 is an absolute sealed LC 183 linear encoder for highly accurate linear position measurement on machine tools and automated machining systems. This version has a measuring length of 1040 mm and an accuracy of 5.0 µm. With a grating period of 20,000 µm and a measuring step of 10 nm, the system provides the fine position resolution required for precise machine axes, closed control loops and repeatable machining results. Data output uses EnDat 02 or EnDat 2.2 with an additional incremental signal. The specified output signal is 1 Vpp and the electrical connection uses a 14-pin connector. Supply voltage is between 3.6 and 5.25 V. The sealed measuring system has IP53 protection and is designed for industrial machine environments when the installation and protection requirements are observed. The documented weight of 5.0 kg supports transport, installation and spare-parts planning. These values provide a clear basis for comparing technical variants. The LC 183 with identification number 557 679-10 is suitable as a type-identical replacement for existing Heidenhain linear encoders on CNC axes and for planned retrofit work. Before replacement, measuring length, accuracy class, mechanical mounting, reference position, EnDat version, incremental signal, connector configuration, supply and control evaluation must be checked carefully. The complete identification number 557 679-10 is decisive because neighbouring LC-183 versions may differ in measuring length, connection and interface configuration. The clearly defined measurement and interface data support targeted spare-parts sourcing and reduce the risk of selecting an unsuitable neighbouring variant during time-critical industrial machine downtime.

FAQ

Frequently asked questions

Contact us
Which measuring data does the Heidenhain 557 679-10 provide?

The LC 183 has a 1040 mm measuring length, 5.0 µm accuracy, 20,000 µm grating period and a measuring step of 10 nm.

What must be checked before replacing the linear encoder?

Measuring length, accuracy class, mounting, reference position, EnDat version, incremental signal, connector, supply and control evaluation must match.

Is there a guarantee?

Yes, we provide a 14-day functional guarantee for used items. This means the component must be operational when received.

Please note that the guarantee only applies when the warranty seal is undamaged.

If a defect occurs within 14 calendar days, please contact us in writing. Subject to availability, we will provide a replacement or refund the full purchase price after return.

Further details are provided in the terms and conditions supplied with your quotation.

How quickly do you dispatch and which shipping options are available?

We generally dispatch immediately - in many cases on the same working day. For particularly urgent requirements or machine downtime, we find a suitable solution as quickly as possible and provide a specific delivery window on request.

Express shipping or collection from our premises is also possible, depending on the situation. State your requirements during the ordering process or contact us directly.

We ship worldwide and work with reliable shipping partners, from parcel services to freight forwarding. Freight shipments normally require some preparation so the goods arrive safely and undamaged.

Which payment methods are available?

Payment is normally made by bank transfer against invoice. Payment is due within 10 calendar days of receiving the goods.

As a rule, we offer purchase on account for all customers. In individual cases, such as new customers or particularly high-value components, we may agree advance payment. This decision is made individually and communicated transparently.

Can we return items if they were ordered incorrectly?

Because we sell exclusively to business customers (B2B), there is no general right of return and no consumer right of withdrawal.

Please note that returns of functioning goods are generally excluded. In justified exceptional cases, we can assess an individual solution, but this is not the standard procedure.

Is there a discount when ordering several items?

For larger order quantities or several items of one type, we can offer individual discounts.

Simply send us a quick enquiry - we check availability and will gladly prepare a tailored quotation with quantity pricing.

Do you also purchase industrial spare parts?

Yes, we also purchase automation components, such as frequency inverters, PLC assemblies, panels, servo motors and CPUs. Components from Siemens, Lenze, Schneider Electric, Control Techniques or Heidenhain are especially sought after, and other brands are also possible.

The process is straightforward: email us an inventory list or overview photos at info@reha-industriekomponenten.de. We calculate a market-based purchase price and send you an offer.
